PROJECT2 Material FILL showing on Archicad 26 and Archicad 27 but won't show on Archicad 28 - BUG?

[concepsys]

Hello, I have spent a few hours trying to understand why is that an object will show the fill that I defined in Master script on plan view on Archicad 26 and Archicad 27 but not in Archicad 28.

I have searched for new features in Archicad 28 GDL, tried different type of project2 { } options. Nothing works.

I am beginning to believe it may be an Archicad 28 bug.

I created an example object with just the needed code.

In Archicad 26 an 27:

The object's fill shows as a green grid in this image.

On Archicad 28 the same exact object. Can´t get the fill to show.

  

They will both show a correct texture in 3d.

Any help to solve this problem or Archicad Update to solve this (if it is in fact a bug) would be appreciated.

I am attaching the test object below.

Interesting! I can see the same behaviour and replicate it.

I thought at first it was an issue of not using CPRISM_{4}, but switching up the command does nothing for me. Deleting the 32 from the status at least gives a colored fill, but no fill lines!

Maybe @Peter Baksa or @Magdolna Marosvari know anything about this?

Really smells like a big bug – luckily it only seems to be related to custom defined fills/materials.
